New Sex Offender Law

The ban does not apply to parents and guardians of students if those adults have permission from school administrators.

"If we know where the sex offender who is registered lives, now we want to know if they're walking their dog close to the school, or if they're near the school in some fashion," explained Bill Tackett, Cole County prosecuting attorney. "So it's just another way in tracking the sex offender."

Tackett said there are about 100 registered sex offenders in the county. However, he said unregistered sex offenders are the most serious threat to students.
